A reversible cycle using an ideal gas as the working substance consists of a isentropic compression from and initial temperature to 555°K, a constant volume process from 555° to 835°K, a reversible adiabatic expansion to 555°K, a constant pressure expansion from 555°K to 835°K followed by a constant volume process to the initial temperature. Draw the cycle on P-V and T-s diagrams and determine the initial temperature, ($\gamma$ = 1.40). Also compute the workdone.
